Daniil Dubov tested positive for Covid-19 on the final rest day of the Tata Steel Chess Tournament and forfeits his last three games against Rapport, Praggnanandhaa and Carlsen. Earlier three coaches tested positive and had to go into isolation. One of them was with Dubov, so he was asked to play round seven with a mask, which he refused and forfeited against Giri. With forfeits against the three tournament leaders Carlsen, Giri and Rapport, the impact of his exclusion is limited.
